- Application filed April 4,

To all/whom iii-may concern: I I 4 Cor, a citizen of-the UnitedStates, residing at Concla, in the county ofCaribou and State 5 of Idaho, have invented certain new and useful Improvements in Oil-Cups, of which the followingis'a specification. I

specifically adapted for application to connecting or pitmanrods oif-all types of machines, with which lam'now familiar, itbemg of course understoodthat I do notlimit myself to the applicationof mydevice to pitman or connecting rods, as-in thefuture practice, the device will operate equally as well as in conjunction with the movable ele ments of all machinery, the nature of the same being such as to automatically feed the oil to the parts when the machines are operating, but which will absolutely cut oil the flow of oil when the machines are stopped {for thereby overcominga ---grea,t wastage of fuel; 7 Y

A further-purpose of the invention is the provision of such an oil cup, that is come paratively simple of construction, and that will operate efficiently and eilectivelyunder all conditions, which may be installed and maintained at a minimum expense, and

wherein the component parts will be so -arrangedandcorrelated as toreduce the posslbllity of derangement to a minimum.

The nature and advantages of the inven-- tion will .be better understood whenthe fol-- lowing detailed description is read in con- I nection with theaccomp'anyingdrawings,

the invention residing in the construction,

combination, and arrangement of parts as r the opemng' of a neck 18, theupper end of detail vertical cross see- 1923. Serial no. 629,771

. device embodies the provision of an open Be it known thatI, ROBERT HARRY Moended cylindrical 'casing-5, the lower end of which is positioned within 2 the plate 6, formed upon the upper end of a wellknown typeoffitting 7, it being understood that between the lower end of thiscasing, and the sald platen, there is interposed a' packing In carrying outthe present invention, it is mypurpose to provide an oil cup that' isring 8: U-ponthe top end of the casingn is aclosurecap- 9, thesame'being formed which is a sleeveor collar=10; the same being formed with internal screw threa'ds for the reception of ascrew threaded filler plug 11, whereby lubricant may be placed into'thc cup whenthe plug is removed. As a means for retaining this :plug within the'sleeve or collar 10, there is provideda set screw 12, that engages through an opening in the col lar and binds against theisaid filler plug. The platen upon the end of the said fitting 7 is centrally formedwith an upwardly extending 'neck 13, the same being provided with a central opening coextensive with'thelength-"of the: passage through the fitting 7. Communicating withthe'interior of the cup and the said passagethrough the fitting 7 are inwardly extending and downwardly v V inclined oil passages 14." r

The said "neck :13 is externally screw threaded,- =and has positioned thereon what may be-termeda sleeve 15, the opposite sidesof this sleeve being formed with relatively elongated vertically extending arms '16, it-

being noted that thiselement is maintained in adjusted positions upon the neck, through the medium of-bindingscrews 17; The com municating-ends of the said passages 14 provide avalve seat for the headed end of the valve rod 18,- and is" freely movable within slotted at 2 1 for engaging 'over a relatively elongated set screw 25, that is carried by the weighted end of the arm 22, the head of the said screw adapted for contacting the arm 23, for limiting the downward swinging movement of the arm 20, upon its pivot 21.

As a means for raising the arm 20 upon its pivot for consequently forcing the valve rod 18 downwardly, for preventing the passage of the lubricant from the cup to the fitting 7 there is connected to this arm at a point forwardly of its pivot one end of a hair spring 26, this spring being coiled around a cross shaft 27 between the upper ends of the arms 16 of the neck 13, and secured thereto. The opposite end; of this shaft projects outwardly of the arms 16, and one end carries a finger piece 28, while upontheopposite end thereof is a ratchet wheel 29. Pivoted upon the arm 16 adjacent said' ratchet wheel 29 is a dog 30, normally forced into engagement with the teeth of the wheel, through the instrumentality of a band spring, it being of course understood that the shaft 27 may be rotated for increasing or diminishing the tension of the spring.

The cylindrical casing 5 is formed upon one side with an annular projecting portion 32, the front end thereof being open for the reception of a sight glass 33. For maintalning certain elements of the cup in their assembled relation, there is positioned'upon the plate 6 of the fitting 7 a relatively ovalshaped plate 34.," the same being provided with a comparatively large central opening 35, for permitting of theengagement of the plate over the fitting 7. Adjacent the opposite ends of the member 34, are formed vertically extending rods 37, the upper ends thereof being screw threaded and adapted for engagement through openings 38 formed within the opposite ends of a plate 40, and is somewhat similar to the plate 34, it'being of course noted that this plate is positioned upon the top cap 9.

For permitting of the engagement of'this plate over the sleeve or collar 10, the same is formed with a central opening 41, and when the two plates are assembled as shown more clearly in Figure 1, retaining nuts 42 are positioned upon the said screw threaded ends of the rods 37.

In view of the above description, it will at once be apparent that when my improved oil cup is positioned upon a movable element of a machine, such as a pitman or connecting rod, the movement thereof will'occasion a rocking movement of the arm, 20, in view of the weighted end 22. Upon a downward rocking movement of this arm, the valve rod 18 will be raised forconsequently permitting the flow 'of'the oil from the cup through. thefitting to the part to be oiled. 'As soon as the machine is stopped, the spring 26 will maintain the valve rod 18 in its downward Although I have herein shown and 'de-.
